Abstract

The utility model relates to a portable folding grassland sample box, which is formed by eight equal-length strip-shaped plates that are connected by hinges. The eight equal-length strip-shaped plates (1, 1a, 1b, 1c, 1d, 1e, 1f, 1g) are connected by seven hinges, and the seven hinges (2, 2a, 2b, 2c, 2d, 2e, 2f) are staggeredly installed and fixed at the inner side and the outer side of the two-end joints of the eight equal-length strip-shaped plates; the connection positions of the four hinges (2, 2b, 2d, 2f) installed at the inner side are respectively provided with right-angle fixed parts (3, 3a, 3b, 3c), one ends of the right-angle fixed parts (3, 3a, 3b, 3c) are respectively fixed with the adjacent strip-shaped plates, and the other ends are movably connected with the adjacent strip-shaped plates in a hanging way respectively. In the utility model, the equal-length strip-shaped plates are connected through the hinges, so that the equal-length strip-shaped plates can be rapidly surrounded to form a square with each side of one meter during use at site, and the working efficiency is high; the boundary of the sample box is regular, so that the accuracy of the survey data can be ensured; the length of the folded grassland sample box is only 50 cm, so that the portable folding grassland sample box is convenient to carry and occupies small area.

Description

Portable folding meadow sample prescription frame

Technical field

The utility model relates to the sample prescription frame that field study is used, particularly be a kind of portable folding meadow sample prescription frame.

Background technology

In the field study of agricultural research,,, usually need in the regulation area, to investigate sampling with sample prescription for research provides foundation in order to obtain the various related datas such as bio distribution quantity in the institute survey area fast.Traditional way is to make measurer with tape measure or rope, measures a length of side on selected position, measures three isometric limits and pros of previous limit coiled again, as selected regulation area, takes a sample in area then.The sample prescription that this method is determined, irregularity boundary causes investigation result inaccurate, inefficiency; Use the fixedly sample prescription frame of reinforcing bar weldering system, carry inconvenience.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of portable folding meadow sample prescription frame at the problems referred to above, and this sample prescription frame can quick and precisely be measured, and easy to carry.

The utility model is achieved through the following technical solutions: this portable folding meadow sample prescription frame is connected and composed by elongated plates hinges such as eight, connected successively by 7 hinges between the elongated plates such as eight, apposition position medial and lateral, two ends are staggered between elongated plates such as eight installs and fixes for 7 hinges; Be installed in four inboard hinge junctions the right angle fixture is housed respectively, an end of right angle fixture and adjacent stripe board are fixed, and the other end and the activity of adjacent bar plate articulate.

Adopt the good effect of technique scheme: the utility model will wait that hinge connects between the elongated plates, can surround a length of side during on-the-spot the use fast and be one meter square, high efficiency; Sample prescription edge circle rule can guarantee the accuracy of enquiry data; Pack up back length only for 50cm, easy to carry, the harvesting floor area is little.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the structural representation that the utility model is turned up state;

Fig. 3 is the side structure synoptic diagram of Fig. 2.

Among the figure: 1,1a, 1b, 1c, 1d, 1e, 1 f, 1 g stripe board, 2,2a, 2b, 2c, 2d, 2e, 2f hinge, 3,3a, 3b, 3c right angle fixture.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation, and as shown in Figure 1, portable folding meadow sample prescription frame is connected and composed by elongated plates hinges such as eight, and the length of every stripe board is 50cm.Hinge 2 is fixedly mounted on the inboard between elongated plates 1 and the elongated plates 1a, hinge 2a is fixedly mounted on the outside between the elongated plates 1a other end and the elongated plates 1b, hinge 2b is fixedly mounted on the inboard between the elongated plates 1b other end and the elongated plates 1c, hinge 2c is fixedly mounted on the outside between the elongated plates 1c other end and the elongated plates 1d, hinge 2d is fixedly mounted on the inboard between the elongated plates 1d other end and the elongated plates 1e, hinge 2e is fixedly mounted on the outside between the elongated plates 1e other end and elongated plates 1 f, and hinge 2f is fixedly mounted on the inboard between the elongated plates 1 f other end and elongated plates 1 g.Right angle fixture 3 is installed at hinge 2 places, and right angle fixture 3a is installed at hinge 2b place, and right angle fixture 3b is installed at hinge 2d place, and right angle fixture 3c is installed at hinge 2f place.One end and the stripe board 1a of right angle fixture 3 fix, and the other end and stripe board 1 activity articulate.An end and the stripe board 1b of right angle fixture 3a fix, and the other end and stripe board 1c activity articulate.An end and the stripe board 1e of right angle fixture 3b fix, and the other end and stripe board 1d activity articulate.An end and the stripe board 1f of right angle fixture 3c fix, and the other end and stripe board 1g activity articulate.

Elongated plates such as eight connect the back when launching is straight line, and surrounding the back, to form the length of side be one meter square just, and stripe board 1 does not have hinge to be connected with the apposition position of stripe board 1g.

Fig. 2 is the structural representation that the utility model is turned up state, and Fig. 3 is the side structure synoptic diagram of Fig. 2.Fig. 1, Figure 2 shows that to turn up and draw back state signal in, with after when turning up, elongated plates such as eight successively closing together, the length after turning up is 50cm, and is easy to carry.
